作为一名学生, 作为一名iOS开发学习者, 我个人浏览信息包括博客, 更多的选择移动终端。然而, csdn并没有现成的客户端(不过有个web版的)。
之前曾经看到一款开源的导出工具, 但是它是基于Windows平台的。导出的也仅仅是PDF格式。而且, 对于文章的导出, 需要精确URL。无法做到边浏览别导出。
另外, 我想实现的是, 可以在没有网络的情况下, 浏览自己收藏的文章。并且, 对于自己收藏的文章, 可以分类管理。
最关键的是, 对于自己的文章, 可以做一个备份。我曾经遇到过这样一件事, csdn账号密码泄漏, 使得他人登录我账号发表垃圾博文, 导致我的博客被封一天。那时候, 我的博客记录了170篇自己的学习点滴, 没有备份, 可以想像那时候我有多慌。可见, 备份自己文章的重要性。
基于以上种种原因, 这款基于iOS平台的博客导出工具应运而生。
本文章正在参与2014年csdn博客大赛。如果您觉得, 对您有所帮助, 希望能投上宝贵的一票。

看到这里, 如果你只是想体验一下这个应用, 想看看源码, 那可以从我的Github中下载。另外, 第一版已经上传到App Store上去了。 正在等待审核。

如果你想了解下整体开发过程, 欢迎继续往下看。推荐下载了源码, 对照着看。
